Specification of Letters Patent.

Patented Dec. 5, 1916.

Application filed May 6, 1916. Serial No. 95,857.

To all whom it may concern:

Be it known that I, JosErH C. DoBY, a citizen of the United States, residing at Grand Valley, in the county of Garfield and State of Colorado, have invented certain new and useful Improvements'in Gambi'els, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to certain improvements in gambrels and it is an object of the invention to provide a device of this general character having novel and improved means whereby the carcass to be suspended may be elevated with a minimum of effort.

Furthermore it is an object of the invention to provide a novel and improved device of this general character wherein a flexible hoisting member is employed and wherein automatic means eoact with said flexible hoisting member for maintaining the carcass in elevation.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved gambrel whereby certain important advantages are attained and the device is rendered simpler, less expensive and otherwise more convenient and advantageous for use, all as will be hereinafter more fully set forth.

The novel features of the invention will hereinafter bc definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein Figure l is a view partly in elevation and partly in section illustrating a gambrel constructed in accordance with an embodiment of my invention; Fig. 2, is a diagrammatic View illustrating the arrangement. of the flexible member M as herein embodied; Fig. 3 is a longitudinal sectional view taken through the device as herein disclosed with certain of the parts omitted and other parts shown in elevation; Fig. 4 is a fragmentary longitudinal sectional View taken at right angles to the section in Fig. 3;-Fig. 5 is an elevational view of the outer end of one of the blocks as herein included with certain of the parts omitted for clarity in disclosure; Fig. 6 is a sectional view taken through the holding member herein employed; and Fig. 7 is a sectional view taken substantially on the line 77 of Fig. 6.

As disclosed in the accompanying drawings, 1 denotes a block of predetermined dimensions preferably substantially rectangular in form and provided at one end with an opening 2to afford means whereby said block 1 may be supported in a desired posiiion and further provided with a series of Y longitudinally alined openings 3 in each of which is mounted a pulley at.

The lower end of the block 1 is provided with the longitudinally disposed opening 5 in communication with the adjacent opening 3 for a purpose which will hereinafter be explained.

6 denotes a second elongated block having its upper portion provided with a longitudinal bore '7 below which is arranged a series of longitudinally alined openings 8 preferably two in number and in each of which is mounted a pulley J. The longitudinal or side faces of the block 6 are provided intermediate their lengths with the slots 10 in communication with the bore 7 and extending a predetermined distance inwardly of the lower end of said bore. The

upper end of the block 6 is bifurcated and pulley 15.

The lower portion of the block 6 is preferably enlarged transversely and has the outer or lower portions thereof at opposite sides of its transverse center reduced in thickness, as indicated at 16, to afford webs 16 adaptedto extend within the kerfs 17 of the bifurcated inner extremities of the spreading arms 18, said spreading arms 18 being pivotally enga ed, as at 19, with said webs. The outer or ree ends of the spreading arms 18 have pivotally engaged therewith the hooks 20 adapted to be engaged in a conventional manner with the carcass to be sus ended.

ne of the spreading arms 18 has secured to its inner face and adjacent its free end the bracket 21 with which is pivotally engaged I the arm 22 extending through an opening 23 produced in the second spreading arm 18,

and the lower face of said arm 22 is provided with the teeth 24 adapted to engage by gravity the catch pin 25 intersecting the opening 23 whereby it will be perceived that as the spreading arms 18 are separated, the arm 22 serves to prevent inward or retrograde movement of said spreading arms.

- Secured to the outer face of each of the spreading arms 18 adjacent the lower ends thereof is an extremity of a flexible member 26 which extends within the bore 7 through the lower portion of the slots 10 and beneath the pulleys 15, whereby it will be perceived that upon upward movement of the flexible members 26 within the bore 7, the spreading arms 18 will be caused to separate, The upper or connected extremities of the flexible members 26 are suitably secured to the portion 27 of the flexible member M, said portion 27 being disposed through the bore 7 of the block 6 and upwardly through the opening 5 of the block 1 and over the pulley 4 in the opening 3 immediately adjacent the lower end of the block 1. The member M is then extended downwardly, as indicated at 28, and passes under the upper pulley 9.

The flexible member M is then extended up-.

\vardly, as indicated at 29, and is extended over the second pulley 1 above the lower end of the block 1 and continues downwardly, as indicated at 30, and passes beneath the lower pulley 9, as at 31. The

flexible member M is then continued upwardly, as indicated at 32, and passes over the uppermost pulley 4 and is then extended, as at 33, to a locality whereby the requisite pull may be imposed upon the member M for elevating or raising the block 6 and the carcass with which the spreading arms 18 may be engaged.

34 denotes a block adapted to be suitably anchored and having one end portion provided with a bore 35in communication with a recess 36 in a side of said block 3% and in .which recess 36 is rotatably mounted the pulley 37. The portion 33 is directed through the bore 35 and out through the re- ('ess 36 beneath the pulley 37. At a point above the recess 36 the opposite sides of the block34 are provided with the openings 38 ,also in communlcation with the bore 35 whereby means is afforded to permit the jaws 39 to engage the part 33 of the flexible member M in order to prevent return movement of said portion 33 of the flexible mem ber M which would otherwise result in the lowering or downward movement of the block 6 and the carcass supported thereby.-

lhe jaws 39 are normally forced inwardly to operatively engage the flexiblemember M through the medium of the expansible members 10 herein disclosed as conventional coil springs interposed between the side faces of the block 34 and the upwardly extending tails 41 of the jaws 39.

It is to be noted that the. returned portions iaoaeao 29, 30, 31 and 32 overlie opposite faces of the blocks 1 and 6 and in order to prevent entanglement of these returned portions, 1 find it of particular advantage to provide the opposite'faces of said blocks 1 and 6 at their opposed ends with the transversely directed plates 42 provided in their under faces with the channels 43 disposed longitudinally of the blocks 1 and 6 and through which the returned portions 29, 30, 31 and 32 of the flexible member M are disposed.

in the operation of the device, the hooks 20' are properly engaged with a carcass whereupon the requisite pull is imparted upon the flexible member M which results in the elevation of the block 6. When the block 6 comes into contact with the block 1, the continued pull upon the flexible member M will result in an. upward or separating movement of the arms 18 so that it will be perceived that the carcass may be readily inexpensive nature and is particularly well adapted for use by reason of the convenience and facility with which it may be assembled, and it will also be obvious that my invention is susceptible of some change and modification without material departure from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice- 1 claim;
